Contact: Patrick Louden Tel: (561) 796-6793 Web Site: www.pw.utc.com Pratt & Whitney Space Propulsion – RD-0146 To meet evolving expendable launch requirements, Pratt & Whitney is offering the RD0146, a cryogenic upper-stage engine designed and developed by the leading Russian cryogenic rocket engine developer, Chemiautomatics Design Bureau (CADB) of Voronezh, Russia. Designed to produce 22,000 pounds of thrust with a minimum vacuum ISP of 451 seconds, the RD-0146 employs the expander cycle, giving the engine greater operating range capability including multiple firings in space. CADB has developed over 60 different rocket engine models during its 60-year history, including the RD-0120 engine that formed the core for the Russian Energia vehicle. The RD-0146 demonstration phase is now underway with engine certification expected in 2004. Characteristics Thrust: 22,000 lb Weight: 534 lb Specific impulse, vacuum (minimum): 451 sec Cycle: Full Expander Propellants: LH2/LOX Mixture Ratio: 6.0 Restarts: Multiple Pratt & Whitney will make the necessary modifications and certify the engine for any non-Russian (CIS) vehicle application. Production engines will be delivered and supported by Pratt & Whitney.
